To (tZZ whom it nul concern.-

Be it known that I, THOMAS S. TILES, a citizen of the United States, residing at Albany, in the countyof Albany, State'of New York, have invented certain new and useful Improvements in Sad-Iron Heaters, of which the following is a specification, reference being had therein to the accompanying drawings. This invention relates to sad-iron heaters, and more particularly to a casing adapted to contain such a heater and to. prevent the radiation of heat therefrom.

The invention has for an object to provide a casing having an outlet-aperture adapted to convey the heat radiated from the burner, and thus maintain the case in a comparatively cool condition.

A further object of the invention is to supply such' a casing with a burner-chamber adapted to receive and contain the burner and provided with an outlet by and through which the products of combustion and sur-i plus heat may be conveyed from the burner-. chamber. I p v V The invention has for a further object to provide novel and improved meansfor. supporting the heater and for supplying thereto the fuel for combustion and the necessary. air to promote a circulation between the -burner-' chamber and the casing'to maintain the latter in a cool condition and prevent radiation of heat from the chamber where the heater is located.

Other objects and advantages of the invention will hereinafter appear in the following description and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a vertical sec tion through the heater with the conductingpipe shown in dotted lines. Fig. 2 is an elevation showing a plurality of heaters connected to a conducting-trunk, a part of one pipe being broken away; and Fig. 3 is ahorizontal section on the line 3 3 of Fig. 1.

Like letters of reference indicate like parts throughout the several figures of the drawings.

The letter A designates an outer casing adapted to receive and contain a burnerchamber 13, into which a suitable burner 0 extends. The casing and parts contained therein may be supported by any desired means; butit has been found very convenient to support the same in an inclined posi' tion, asshown in Fig. 1, by means of a bracket D, adapted to be attached to a fixed substan tially vertical surface. The casing Ais provided with an outlet A- for the heated air within the same and-With an air-inlet open ing A at the opposite end from said outlet, While the burner-chamber is provided with a similar .outletBlwithin the outlet A and of a smaller diameter. The burner-chamber is also provided with an inlet B adapted to supply the necessary air to permit and maintain a proper combustion. The burner-chamber and casing are of such relative dimensions as to leave an air-space between the same, so thatthe heat radiated from the burner-chamber B causes a current of air through said space, which heated air is conveyed to a point of discharge by any suitable meansfor inf stance, an uptake-tube E. The heater hereinbefore' described provides a structure by which the casing may be maintained in a comparatively cool condition and from which no material amount of heat will be radiated to theroo'm.

Y .The details of construction of the several parts maybe changed as well as the configuration thereof; but as illustrating a desirable form of the apparatus the casing A has been shown as provided with a removable cover A held in position by any suitable means'for instance, bolts Aand provided at its central portion with an openiu g conforming substant-ially to the outline of a sad-iron and provided with inwardly-curved edges or margins Ai'whereby when the iron is placed within the receiving-opening said opening is prac-.

tically closed thereby and the transmission of heat to the apartment or room containing the heater is largely obviated. The casing A is further provided with spacing projections or lugs A, upouwhich the burner-chamber B will rest. 7 receiving opening B lying directlybeneath the iuwardly curved or rolled walls A of the casing, and the walls of the casing or of the burner-chamber-may be coated or packed with any suitable non-conducting material, as indicated at A which will prevent the This chamber is provided with a ready transmission of heat through the metallic casing orany joints therein. The chamber 13 is provided on one face with a threaded socket B adapted to receive a threaded connector D, extending from the bracket D, while at the upper portion of said chamber a neck or collar B is formed, through which the burner-tube 0 passes and within which it may be secured by means of a suitable set-screw B or other device. This chamber is also provided upon its inner walls with seats or brackets B adapted to support the iron.

The form of burner shown is especially adapted for the use of air and gas and is provided with jet-openings O, formedin the tube 0, one end of said tube being suitably stopped or filled by means of a plug C while at the opposite end of the tube 'an air connection 0 is provided and agas connection 0 These are provided with any desired form of stopcock C for regulating the pressure or amount of fuel and are connected by tubing 0 with a SuppIy-pipe'C which may contain air under the normal pressure of the atmosphere or under a greater pressure, if desired, and the gas connection with a similar supply-pipe 0 It has been found desirable in use to locate a number of these burners above and adjacent to an ironing-table, so that a single supplypipe extending the length of said table is adapted to furnish the necessary fuel for a number of heaters, while the heat or products of combustion from said heaters are conveyed by tubes E to a main trunk or pipe Eand discharged at any suitable point.

It will be seen that the manner of supporting the heater hereinbefore described maintains the same in an inclined position directly in front of a person handling the iron and the structure of casing around the burnerchamber effectually prevents the radiation 'or conduction of the heat into the room, thus maintaining the same at a desirable and agreeable temperature, which is very difficult to obtain in laundries Where a number of iron heating devices are in use. Furthermore, the structure of heater occupies but little room, so that it can conveniently be applied in private dwellings and connected with an ordinary gas-fixture, thus providing a means for quickly and effectually heating an iron with: out raising the temperature of the room to the undesirable degree heretofore necessary with the ordinary structure of heating device. The rolled or inwardly-curved receiving-opening provides a guide for introducing the iron into the burner-chamber and atthe same time maintains such a close connection with the edges of an iron as to prevent the escape of from the burner-chamber and for maintaining around and aboutsaid chamber a current of air by which the casing is rendered cool and a draft maintained to carry all unpleas- I ant odors from unconsumed fuel or gas and radiated heat to a suitable point of discharge. Having described my invention, What I claim as new, and desire to secure by Letters Patent, is'- 1. A sad-iron heater comprising a doublewalled casing having an iron-receiving open- 4 ing and provided withinlet-apertures to ad t mit air to the space between the walls of the casing and to the inner casing, supportingbrackets within the inner casing and beneath fo T the receiving-opening, and a burner beneath said brackets; substantially asspecified.
